Several Rapture Questions
The main one is this: I'm quite confused over the specification of vel. response in the modulation section. We have two values, velocity intensity and velocity track. The doc. describes them respectively as "This controls the intensity in which the Note-on velocity affects the modulation depth" and "To edit how velocity affects the current envelope's value, drag the Vel Track field up or down". These sound like exactly the same thing. Can anyone clarify what the difference is? Also, I think I know the answer for the next two, but want to have my understanding confirmed. Keyboard tracking in the mod. section only affects the envelop depth, right? There's no way to get it to apply to the timing of the envelope? I can't spot any way to make the an element a slave to another (i.e., to have the slave start it's waveform based whenever the master starts its own, irrespective of where the slave is in its cycle). Not a biggie, but I'm just curious. Thanks in advance for any help.

I hope I can help clear this up for you. First, VelTrack in all 6 modifiers (Pitch, Cut1, Res1, Cut2, Res2, Pan, Amp) is always active, independent of the envelope. Demonstration is easy. Start fresh -- Initialize the program. Enable Element 1 only, and load a simple Saw waveform (like 016 Saw Mini). Staying in E1, enable the DSP section with chain #1 or #2, in which the filters are in serial. You want all the signal to go through one filter. Set Filter 1 to LP6, Reso = 0, Cutoff = 95Hz. All other DSP disabled. In the modifiers section for E1, disable all envelopes, especially the Cut1 Envelope (Status = off). Notice all EG parameters are grey except VelTrack--there's your clue. Make sure E1 is enabled down in the Mixer section, and crank the Vol level to 88%. No other elements should be disabled. Open the Master volume to 80%, and no limiter. OK, now, play some notes around middle C. Use different velocities, and note that no matter what you play, you don't hear much until you play down around C3 and below. At C4 (middle C) and above, nothing -- all filtered out. You can confirm by using a Spectrum analyzer in the Rapture Fx bin -- you might see some wave action, but too low to be audible. Next, up the E1 EG VelTrack value to 1200. Just change the 1 parameter. Leave the envelope disabled. Note the difference in what you hear at different velocities around C4. This is the effect of VelTrack. Perhaps this is the only difference between VelTrack and Vel.Intensity? The docs aren't very clear. Maybe Rene will contribute more information on this? As for your other question -- Key tracking in Rapture does not effect the envelope timing using the front end controls, but, using the Mod Matrix, you can use Keyboard as an input and many envelope parameters as the Destination. Click the icon near the program name that looks like a 5-pin MIDI port to open the Modulator Matrix. As for slaving one input to another, you will have to present a specific question here to get a specific answer. Rapture is an excellent tool for soundesign, and has many builtins to "push the envelope" so to speak. Have you discovered SFZ format yet? Rapture and Dim Pro both support SFZ files, which have their own set of DSP processing macros you can use to tweak your sound files. The documentation is found within the website's "Support" section. regards, -- kwgm

Thanks for the reply, kwgm. Let's take my points in reverse order. As for slaving one input to another, you will have to present a specific question here to get a specific answer. I think a common term for what I'm describing is hard sync. I'm pretty sure both Pentagon and Z3ta offer it as an option. The idea (I've read about this but never actually experimented) is this. You have two oscillators running a wave (say a saw for sake of discussion). When running independantly, if osc. 2 cycles the wave at a frequency 1.5 times that of osc. 1, you hear a fifth interval. With osc. 2 hard synced to osc. 1, it restarts its cycle whenever osc. 1 starts its cycle. You no longer hear an interval, but you get varying overtones as you alter the ratio of playback frequencies. That is, until you get to a ratio of 2, at which point it kicks back into sync and you hear an octave. I wanted to play around with this on Rapture, but don't see how it can be done. Again, not a biggie ... just a matter of curiosity. using the Mod Matrix, you can use Keyboard as an input and many envelope parameters as the Destination. Wow! What flexibility. I'd read about this in the doc. but had not gotten around to checking it out closely. Very impressive. Staying in E1, enable the DSP section with chain #1 or #2, in which the filters are in serial. You want all the signal to go through one filter. Set Filter 1 to LP6, Reso = 0, Cutoff = 95Hz. All other DSP disabled. There were several things in your recommendation that I'm a bit confused about. For starters, though, are you saying that the two cutoff pages in the modulators section are tied to the two filters in the DSP section? I thought that to be the case intially, but then became convinced the DSP filters are "element global" and not associated with individual notes. The clue that this is so can be found in the Mod. Matrix, where the various parameters of both types of filter are different, separate destinations. I'll experiment more (after I've recovered from a nasty cold that's just come on) and report back any interesting findings. In the mean time, BRock, I'm disappointed you haven't weighed in on this subject. I'd love to know what your thoughs are on the question.

Hi there, OK, now I understand what you're saying. No, you cannot sync one waveform to another in Rapture. There are other features that approach sync -- for example, using the multi-voice and detune features for each element, but not between elements. There are also multisamples that have been sync'd in another synth (maybe Zeta?), for use in an element. As far as your last point, yes -- the modulation envelopes are for the entire element and cannot be assigned to individual zones within the element. Sorry if I misunderstood. If this is what you need, perhaps you can use multiple elements with identical settings, using different Zones -- will this work? (By Zone, I mean a specific range of notes.) With 6 elements, that can cover a lot of territory. I'm thinking that Tom Brock is out of town for a few days. I'm sure you'll hear from him when he returns. Don't forget to explore SFZ format. Here's the link: SFZ File Documentation

Thanks again for the response, kwgm. I've been reading and rereading the Rapture doc plus the Rapture section in the Cakewalk Synthesizers Presets to Power Users book. A few things are clearing up. For one thing, there is powerful keyboard tracking capabilities right in the envolope window, the editing of which is triggered with the K key (V gets you velocity tracking). I missed it in the official doc. but there's an illustration in the CWPPU book. So, there seems to be three ways to do this, one for the entire envelope and the other two for individual segments. Sheehsh! Also, the CWPPU book offered this distinction between the two vel. settings affecting env. intensity: vel->int.: "This controls the extent to which velocity affects the initial level of the envelope" vel track: "This control affects the extent to which MIDI velocity affects the envelope's output level." [implying the entire envelope, not just the first level?] Finally, after more reading (and rereading ... at the moment I'm spending a lot of time in bed trying to get over a nasty head cold), I think it's clearer that the cutoff and resonance envelopes are tied to the two filters in the DSP section after all. There are just so many options, it can be a little overwhelming trying to fully get the lay of the land. I last worked with synths back in the early 90s (Roland and Korg boxes mostly). I feel like a moderately compentant Cessna pilot sitting in the cockpit of a state of the art fighter jet. Too many switches, dials and levers! As to your suggesting about learning sfz format, I've started doing just that several weeks ago. One project I'd like to do later this year is to capture some M1 sounds as sample sets available to use in Rapture or DP. If I can get the sample loop points identified, the rest looks pretty straightforward using sfz specifications.

That's great -- I forgot about the keyboard tracking in the envelope. You can also make a loop in there, too. Rapture is very powerful, and one of my very favorite sound design tools. What you may not know is there's an update coming very soon that promises a few more features.. check this out towards the end of the month. Also, Tom (BRock) has written a few tutorials on Rapture programming that are over in the Sonar Wiki. When you're ready, take a look. Have fun!

Here is the link to the Rapture Section on the SONAR User Wiki. Thanks, Bob. It's now bookmarked in my browser. I think I stumbled across it once before but forgot all about its existance.
